CHICAGO, ILLINOIS, A CORPORATION OF INKING MECHANISM FOR PRINTING-PRESSES.

To all whom it may concern:

Be it known that I, MICHAEL A. DROIT- COUR, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Inking Mechanism for Printing-Presses, of which the following is a specification. v

This invention relates to the inking mechanism of printing presse My object in it has been to so construct such mechanism as to render it possible to remove any one'or' more of the rolls whenever that is desirable or necessary, either for the repair or cleaning of the rolls themselves, or to uncover the type cylinder surface so To this end, I provide two are openings in the frame of the press, and locate the bearings of a portion say agroup of three of the composition rolls'in each of such openings, and I also arrange some of the metal rolls of the inking series in open bearings so located with reference to the said groups of com osition rolls that they act as keys to co e the groups in the arc slots of the frame. The composition rolls are all readilyrdetachable from their bearings, so that whenever access to the type cylinder is desired, it is quickly obtained by first removing the key rolls, and then the composition rolls confined by the key rolls. The construction is such also as to permit the quick replacing of the rolls after they have been removed, the invention being intended to save time in the making of changes and repalrs.

The nature of my improvements is fully set forth below, and will be understood from the descri tion thereof and from the accompanying rawing, in which 1atter Figure 1 isa partial side elevation of a press embodying my present improvements; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is an enlarged section of one of the composition roll bearings and Fig. 4 is a section on the line '44 of Fig. 3. Fig. 5 is a section on the line 55 of Fig. 2.

In said drawing 5 represents the side frame of a printing press, or printing cylinder, 7 the impression cylinder, 8 the delivery cylinder, and 9 the feed table feeding the sheets to the crownof the as to permit changes in the forms.

impression cylinder. After printing the sheets may be delivered by the impression and delivery cylinders in the usual manner. The ink well is shown atlO, and it feeds the ink by means of the roll 11 to the ductor roll 12 which, by means not shown, is moved at intervals into contact with roll 11 and is thereby charged with ink. The ink so received is distributed by metal rolls 13, 14, 15, 16, 17 and 18 and the intermediate composition rolls 19, 20, 21, 22, 23, and is supplied to the printing cylinder by form inking rolls 24 to 29 inclusive which are in contact with the distributing rolls 15, 16, and 18. Said rolls 15, and 18 are supported in open bearings. 150, and 180, and so also roll 17 has similar bearings 170, and the inking rolls 24, 25 and 26 have their bearings located opposite an are shaped opening 30 in the side frame of the press, While rolls 27,

28 and 29 have-their bearings opposite a second are shaped opening 31 in the said frame. As shown distributing vroll-18 1ptates in contact with composition rolls 24 and 25, distributing roll 16 with composition rolls 26 and 27, and distributing, roll 15 in contact with composition rolls 28 and 29. With this construction, it will be seen that by removing roll 18, the composition rolls 24, 25 and 26 are all rendered readily accessi- .bleand removable, and that by removing roll 15, the inking rolls 27, 28 and 29 are rendered accessible and removable.

It is desirable that the inking rolls be quickly detachable from their bearings and hence I have used the construction now to be detailed.

Each bearing comprises a plate 40 having an opening 41 in which the journal 42 of the roll is inserted. The roll journal is inclosed in an annular bushing 53 which is slipped inserted into the opening in the plate 40 after the roll journal is inserted in the opening 41. The bushing 53 can be detachably secured in position by a spring 50 attached at one end to the plate 40,

and having its other end bentup as at 51 to form a convenient means for manipulating it, and saidspring is adapted to enter an annular groove 52 in the bushing 53 when the latter is slipped into the opening in plate 40, the bushing being retained by collar 54 and spring 51. To permit the be passed laterally in and outthrough the slot 55. To remove a roll having such spring locked bushing, it is only necessary to lift the spring from the bushing, and slide the bushing endwise on the journal and thus uncover the slot. The plate is sup orted by a base plate 43 and is adjusta e on the latter, which has side ards 44 between which plate 40 mayslitii in obedience to a screw 45 which is rotatably engaged with a lug 43 on the base plate. The plates 40 and 43 both have enlarged registering openings 47 through which asses the attaching screw 48 whereby the iearing is attached to the frame of the press and locked when adjusted, the enlarged openings allowing considerable latitude in adjusting the bearing upon the press." The base plate alsohas a fixed pivot 49, entering a suitable hole in the press frame, on which it may be rocked in efi'ectin adjustments. The bearing may be adjust laterally by means of screws 46 tapped through lugs 46" on the side frames of the press (see Figs. 3 and 4). By removing the screw 48, the entire bearing may be detached from the press, as will be readily understood,

With the construction described, it will be seen that complete access to the upper half of the printing cylinder will be gained by removing rolls 18, 24, 25 and 26, and as already explained, such removal may be 'very quickly effected, and the rolls can be quickly replaced, so that'the loss of time in the use of the ress is reduced to a minimum.

It will be noticed that the form rolls 24 to 29 are uniform in size, and that the intermediate'rolls 19 to 23 inclusive are also unlform in size and of the same size as said form rolls. Also that all said rolls are provided with the readily removable bearings described and uniform in construction. These features render all said rolls interchangeable, so that when any one of the form rolls for instance becomes defective, one of the intermediate rolls can'be substituted for it, and the amount of service ob:

tained' fi'om the rolls be greatly increased thereby.

I do not herein claim the construction of the journal bearings and their adjustable supports, which form the subject matter of a divisional a lication filed October 28th, 1909, Serial 0. 525,091.

In an inking mechanism for printing presses, the combination of a frame havin inder, said slots being open at one end; and a cylinder; with a group of form inking roll bearings attached to the frame beside said slots, inking rolls journaled in-said bearings the journals of the rolls extending through said slots, a removable distributing roll located adjacent the open ends of said slots, said distributing roll confining the form inking rolls in said slots and said form inking rolls being removable when the distributing roll is removed. 4

2. In an inking mechanism for printing presses, the combinationof a press frame havin pairs of upper and lower arcsha ed slots ormed in its sides adjacent the p ate cylinder, each slot being 0 en at one end; and a plate 0 linder journa ed in the frame beside said s ots; upper and lower sets of parallel form inking rolls having their journals extending through said slots, removable bearings for the journals-of said rolls attached to the main frame beside the slots,

and distributing rolls located at the open.

'3. In an inking mechanism for printing presses, the combination of a press frame havin an arc-sha ed slot adjacent the plate cylin er, and a p ate 0 linder journaled in the frame beside said ot; with a plurality of adjustable inking roll bearings opposite and projecting over said slots, form inking rolls havin their journals in said bearings, removable ushings in the bearings for the journals of said rolls, and distributing rolls for supplying ink to said form inking rolls,
